如何在一行中从字符串数组中删除空元素?

你也可以用

"1,2,,3".Split(",".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);

string[] ssss = "1,2,,3".Split(new [] {','}, StringSplitOptions.RemoveEmptyEntries);

string[] ssss = "1,2,,3".Split(new[] {','}).Where(a=>!string.IsNullOrEmpty(a)).ToArray();

var ssss = "1,2,,3".Split(new[] {','}).Where(a=>!string.IsNullOrEmpty(a));
foreach (string s in ssss)
{
    Console.WriteLine(s);
}
